In the last 4 months, I have broke out with the welts the size of quarters and larger. they look like huge mesquito bites. the are all over
my body. they itch extremely bad, they go away for a few hours with benedryl but come right back full force. i was on prednesone for a while for it, but as soon as i came off the meds, it came right back. i cant wear certain cloths because it looks so bad. it drives me insane. what is this???
